I see lots of posts with the numbers for all axles ( 2 or 3 ) combined but almos no data on individual axle loads.
I have read elseware of 2 axle TT being close to 46/54 than 50/50 and of a three axle unit being 30/32/37%
The other part of the important equation is actual side to side variation with few units at 50/50 of that axle's load and some axles being at 45/55%
So unless you have weighed your unit with its full load (food, clothes, water, propane and other "stuff") you are only guessing at how much load you are actually asking your tires to carry.
Even at max sidewall pressure you may be operating overloaded.
All the above also assumes the axles are all in align and none are bent which of course introduces additional dynamic loading.
So as the title of this tread asks... "What is your Real Weights?"
This is primarily why I haven't posted my weights here. The true value of how folks weigh is somewhat limited.
I've had each and every truck and 5W tire weighed (military scales) and I've had CAT scale weights as well. I can tell you that there is quite a difference from side-to-side as well as some differences between from front-and-rear trailer tire weights on my trailer. It also varies when the trailer (or truck) leans when traveling (transverse loads) such as when the road is lower on the shoulder than center or during dips, etc. My first individual tire weight was with the trailer off level to a degree. Almost 1000lbs difference side to side. It is my belief that the single-biggest safety factor is, without a doubt, the tires/wheels.
So, what can you do? With my trailer, I upgraded with tires that were rated quite a bit above the worst weight that I weighed when trailer was NOT level. I now feel comfortable that I've installed the best wheels/tires I could afford. On top of that, a TPMS is in the works. I've taken these types of measures in every safety aspect I can imagine. My piece of mind is worth it.
I hope that the purpose of this thread is to educate folks. If so, these issues could use some more discussion albeit weighing in this fashion is difficult. Good on you for raising the flag!

"Rv Travel", a weekly emailed news publication, surveyed their readers last year and found that only 47% of the 1800 or so respondents, actually knew their "weights". And I believe many of these folks are full-timers or nearly full-timers!
After weighing our truck and fiver at a certified CAT scale, and being very surprised with the actual weights compared to those from the factory, I have a theory that most tire failures are because of inadequate tires for the loads of the fivers. Most people are careful about their psi's and watch the tire temps, but the tires are often just not sufficient enough to carry the loads placed on them.
I changed to GY 114 "H" rated tires 17.5" from the factory "E" rated Duros. The new tires were "fresh" (manufactured within the last 4 months) and will be replaced in four years regardless of the tread condition.
The CAT scale weights really startled me because we don't have the fiver "overstocked", but our fiver is near capacity for CCC. Good luck. amf

I just installed 4 new Goodyear Marathon ST235/80R16 E 123. They have a weight limit of just over 3400 lbs ea. I still have yet to have my 5er weighed, but plan to before next trip. I know these Goodyears are foreign made, but they do have the Goodyear name and the backing of Americas Tire company. It's really hard to find American made trailer tires. So,I feel better than when I had the garbage Duraking 181's. My trailer dry weight tag says 8,130 lbs. I don't believe I have over 4,000 lbs of accessories, I never carry more than 10 gals. of fresh water, and gray & black are always empty, but.....? And I like the info on weighing each tire. Total trailer weight is good to know, but doesn't help if trailer is off-loaded & uneven causing excessive weight on any one tire.

Good points all about weights.
However there is more to the story. In doing extensive research, I ran across www.safetyhitch.com which is a big time game changer. The real issue folks should worry about is not really what their truck will be able to accelerate to highway speed with, but instead concentrate on what their truck will do in terms of stopping power. A secondary issue is the amount of weight in the pickup bed, which under heavy braking causes the front wheels to lose traction/contact with the tarmac.
In 2008, the game changed when the automated safety hitch was invented. There is no real difference in towing ability between a 3/4 ton truck and massive dually equipped. The only value the dually has is an extra set of tires. The Safety Hitch does that and more, by providing a steerable (at low speeds) axle with better brakes than your truck is likely to come with. The biggest advantage is that your front end stays fully loaded, even under hard braking, giving you vastly superior braking and steering. At high speeds, the steerable axle locks up and provides a longer wheelbase to prevent fishtailing. Even a 3/4 ton will now have the capacity for up to 26.000 #s without a commercial license and actually more.

Our 2010 Raptor RP300MP weighs 11020 with full generator fuel tank, no water on board, and a 1500 lb. toy on board,
We pull this with a 2007 Dodge Ram 2500 eight foot bed, quad cab, 6.7 Cummings Diesel equipped with Airlift add on pillows. The truck with full tank came in at 9440 lbs. hitched up to the Raptor. Run with 70 psi rear and 50 psi front on the truck and 80 psi on the trailer quads.
On our recent long trip of near 3000 miles we got as low as 8.7 and a high of 14.3 miles per gallon. The average was 10.8 and we traveled at 65 miles per hour 99% of the trip. Used no oil on the motor with 40k miles. Pulled mountains with no more than one down shift of the six speed Alison. This truck performs very well and rides like a dream-loaded that is.
I am a happy camper!
